The Poundland in Edinburgh (I assume stock varies in different locations depending on what other shops/suppliers have too much of) has Easter eggs! The brand is Cocoa Deli and the only dairy free one is 'dark chocolate mint crunch' so they're not quite a traditional Easter egg, but they're pretty nice. They're a hollow shell and a little smaller than most(60g). Also they're two for £1, at least in the Nicolson Street shop.

if vegan drinks covered off here (have seen hot chocolate mentioned but I eat more of this than drink when scratching around for a chocolate fix Trainspotting style - tip from someone who learnt the hard way, never inhale when eating chocolate powder) - what about Sam Smiths fruit beer? Tried strawberry and cherry (amazing - liquid cherry drops) but haven't tracked down rasberry yet. . .
